DESCRIPTION:Here we show some preliminary results of the hyperspectral inve
 stigation on a paleohydrological environment\, using ASI PRISMA data (Capo
 russo et al.\, 2020)\, with the scope of subsequently comparing them with 
 similar environments on Mars (Zinzi et al.\, 2023). \nThe datasets investi
 gated are located in the Gobi Desert. The first areas were selected on the
  basis of the availability of mineralogical data on rocks revealing a comp
 osition of quartz\, albite\, phyllosilicates and sporadic calcite by means
  of X-ray diffraction (Sekine et al.\, 2020). \nKeeping into account that 
 quartz and albite do not show strong unambiguous diagnostic absorption fea
 tures in the PRISMA spectral range\, we aim at investigating whether their
  occurrence can be deduced from the reflectance values and the whole spect
 rum.\nOn the contrary\, phyllosilicates were found in PRISMA data\, in par
 ticular\, their occurrences seem to be attested by the absorption associat
 ed to Al-OH bond around 2.19 micrometers in the structure of illite\, smec
 tite\, kaolinite. \nUp to now\, we did not observe carbonate-related absor
 ptions in the investigated ROIs. This can be due to neglectable abundance 
 of carbonates at the scale of PRISMA\, but this hypothesis needs further i
 nsights.\nHowever\, the study will include another possible delta in the G
 obi area probably characterized by basaltic composition (Mason et al.\, 20
 21 and references therein) and therefore more similar to Jezero delta mine
 ralogy. \nWe will proceed in the identification and mapping of minerals in
  these areas\, in the view of comparison of water related environments on 
 Earth and Mars.\n\nReferences \n\nCaporusso et al.\, 2020. IEEE IGARSS 202
